The first thing I would do is run ping against it, over a period of time, to see how well “connected” the WiFi channel on the device is. If that’s successful, then you’ll likely need to reach out to SquareConnect via their support function (on their site) to get attention to diagnose the situation.
They typically want to know things like the type/model/make of WiFi router you’re using, along with the FW versions of the SQBlaster device itself.
